CHARLES VALENYIA, OF CHICAGO, ILLINOIS.

CARPET-STITCHING DEVICE.

To all whom it may concern:

Beit known that I. CHARLES VALENTA, a citizen of the United States. residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and uscful Improvements in Carpet-Stitching Devices, of which the following is a specification. 1

My invention relates to stitching machines and particularly to a unitary portable machine for stitching seams of carpets and the like which have been ripped or if desired, for fastening together theadj acent pieces of carpet in the first instance.

My invention relates to a single acting device ofsuch compactness and arrangement as can be used to repair ripped seams of carpets without removing the carpet from the floor, the stitching being done by forming staples and pressing the same through the edges of the carpet. 1

One of the objects of my invention is to provide a simple and eflicient portable car-' means and staple driving means as well as means for holding the edges of the carpet for forming either a butt joint or lap joint.

These and other objects of my invention will be apparent from an observation of the drawings, wherein Figure 1 is a side elevational view of the preferred embodiment of my invention Fig. 2 is an elevational view lookin at the machine from the left hand em? of Fig. 1.

Fig. 3 is a vertical sectional view on line 3+3 of Fig. 1.

Fig. 4 is a top plan view of Fig. 1, and

Fig. 5 is a vertical sectional view, somewhat enlarged, showing certain features of the invention in detail.

The preferred embodiment of my invention which I shall herein describe includes a bottom plate 10, a front plate 11, a side plate 12 and a back plate 13. The back plate 13 is preferably reinforced by a brace member 14 as seen in Figs. 1 and 5. In the bottom Specification of Letters Patent. Patented lay 4, 1920,

to the plate 10 having an offset portion 17 spaced from the plate 10 but parallel thereto and another. portion 18 bent back on itself to. form a space similarly situated with respect to the one between the member 17 and the bottom plate 10. In Fig. 1 this anvil is shown as it appears from the right end in Fig. 2, the purpose being to receive the carpets in overlapping relation to form preferably a lap joint. If, however, it is desired to form a butt joint, the same anvil may be used but the pieces of carpet applied thereto in a slightly different manner, which will be more fully described herein after. I

In the form shown I mount rearwardly of the front and back plates 11 and 13-, a reel or spool 19 supported on arms "20 and which reel is adapted to carry a coil of wire required. The wire 21 is led from the reel or spool through an opening in the feeder bar 22 and through an opening 23 in one of the vertical supports 24. To feed the wire forwardly as required and in the manner hereinafter described I provide the feeder bar 22 with an enlarged opening 25 and pivot therein a plate 26, the lower end of which is provided with teeth 27 for gripping the wire (21 as the bar is rocked about its support 28. The plate 26 is so mounted as to grip the wire 21 in only the forward movement of the bar and to free the wire as the bar is rocked backwardly or toward the spool '19. To'retain the wire in position while the feeder bar'is being rocked backwardly to grip the wire to move the same forwardly, I provide a toothed dog 29 adapted to cooperate with a ledge 30 and which dog 29 is held by means of a spring 31 in engagement with the wire 21. The dog 29 and the cooperating spring 31 act to prevent. the wire from being withdrawn while permitting forward movement thereof by the feeder bar 22.

Mounted between the front and back 21 from which the staples are formed as plates 11 and 13 and the side plate 12 are two relatively reciprocal plungers .32 and provided with pins 36 and 37 between which the short arm 38 of the feeder bar 22 is received and by which the feeder bar is actu-.

ated as the plunger 32 is reciprocated. To maintain the plungers 32 and 33 in upward or normal position as shown in Fig.

3, I provide springs 39 and 40 resting against abutments 41 and 42 secured to the back and front plates and at their other ends engaging shoulders 43 and 44 in the plungers 32 and 33, respectively. 7

Pivoted at 46 between the front and back walls 11 and 13 is an arm 45 curved as shown in Fig. 5 and having an outwardly extending shelf or foot 47 which when the arm is in the position shown in Fig. 5 underlies the ends of the fingers 34 and 35 of the plunger 32. The rear of the plunger 32 has formed therewith a lug 48 which is adapted to bear against the curved portion of the arm 45 under'certain conditions as the plunger 32 is reciprocated to move the foot 47' from beneath the end of said plunger. The

lug 48 and the curve of the arm 45 are soassociated that the foot 47 is retained underneath said plunger for a certain portion of the travel of the plunger which will be more fully explained hereinafter.

The wire 21 is adapted to be fed by the feeder bar and the associated parts forwardly through the aperture 23 in the support 24 and over the foot 47 of the arm 45. The parts are so arranged that the wire is fed forwardly until the front end rests against the plate 12 and there is brought to rest, the position of the various parts being shown clearly in Fig. 3. Thereupon, to form a staple from the wire 21, the plunger 32 is moved downwardly by means hereinafter explained bringing the fingers 34 and 35 onto the wire, the finger 35 acting in conjunction with the face of the vertical support 24 to shear off the wire. Continued movement downwardly of the plunger 32 bends the ends of the wires so sheared over the foot 47 into an inverted U-shaped staple 49. In the meantime, the plunger 33 has started downwardly and as downward movement of the two plungers is continued, the lug 48 acts to withdraw the foot 47 supporting the wire which is now a staple 49 from support thereof and the plunger 33 has been moved to engage the staple 49 and is ready to drive the same through the pieces of carpet or similar material A and B which have been previously inserted in the anvil in the manner described and as shown in section in Fig. 3. Continued downward movement of the plunger 33 drives the staple 49 through the overlapped edges of the pieces of carpet and by engagement of the downwardly projecting ends of the said staple with the portions 18 of the anvil the ends are turned inwardly andthe staple clenched in position in the usual manner of clenching a staple. moving the plungers 32 and 33 downwardly now being relieved the springs 39 and 40 become effective to return them to the normal or inoperative position.

The pressure for end to a portion of the framework of the machine.

It is believed that the operation of my invention has now been clearly pointed out and that one skilled in the art could readily employ the same to fasten together pieces of carpet.

I shall, however, explain the operation of my invention so that the same may be clear. Referring to Fig. 3, pieces of carpet A and B are inserted in the anvil with the edges overlapped. The machine may be brought to receive the edges of a ripped seam of carpet while the carpet is still-on the floor in which instance, the anvil would be moved underneath the edges of'the carpet in the same manner as if the pieces of carpet were brought together in the position shown in Fig. 3. When in this position the handle 50 is moved downwardly by the operator, which downward movement reciprocates first the plunger bar 32 to form the staple. Continued movement of the handle then re.-- ciprocates the plunger 33 which is the driving or presser bar todrive the staple through the carpet, the foot 47 having been withdrawn from underneath the staple in the meantime. When the handle has been depressed so that the staple has been formed and clenched in the carpet, the operator re- By my invention I have provided a simple, efiicient and readily portable carpet stitching machine of such a form as. to be utilized in repairing ripped seams without removing the carpet from the floor, or if desirable, the machine may be utilized to fasten together strips of carpet to make a manual operation as I am aware that it would be possible to apply power means to such a device to accomplish the same result without materially changing any of the operative features.

While I have described more or less precisely the details of construction, I do not wish to be understood as limiting myself thereto, as I contemplate changes in form and the proportion of parts and the substitution of equivalents as circumstances may suggest or render expedient without departing from the spirit or, scope of my invention.

I claim:

l. A machine of the character described comprising in combination a pair of vertically movable plungers mounted for relative reciprocation side by side, means for feeding wire laterally in the path of movement of said plungers, the lower end of one of said plungers being shaped toconstitute a shearing means for the wire and the lower end ,of the other of said plungers being shaped to-set a staple formed from said wire, and a manually operable handle mounted to swing above and across the upper ends of said plungers and having .its lower edge formed to provide cams of differing contours, said cams acting respectively upon the upper ends of said plungers to impart a longitudinal thrust thereto vby wiping across the upper end thereof.
